It's just about the main program (executable). Libs and thus modules
won't be affected. Apps can decide wether they want to support guile
modules written in C++ (and be linked appropriatly).

c++ code being loaded into guile dynamically (i.e. shared libs).

Sorry, there is no definite explanation (at least i didn't find
one). However, I'm going to investigate this more. It seems it may
have to do with most C++ shared libs ending up being linked by gcc
instead of g++ (due to a libtool bug).
